We currently rent out my late mother in laws house. It's an end house on a row of terraced houses. The house has a passageway down the side with doors at either end which belong solely to mils house. It's crystal clear on the deeds. Mil always let the ndn have access to this passageway to get her bins out as a neighbourly courtesy. This carried on for over 20 years with no problems. There is now a new ndn of less than 12 months who is causing problems. She is complaining to the tenants that the passageway smells, it's blocked, they don't take care of the garden etc. The tenants are actually very nice and have tried to be accommodating. The garden is a bit untidy but nothing major and I can't smell anything in the passageway. The ndn was very rude to my husband the other day and I've had enough of her. Is there anything to stop me from telling her not to use the passageway if she's not happy? I can't see anything on the house deeds but of course I don't know what her solicitor discovered when she bought the house. We intend selling the house shortly anyway. I don't want to go to the expense of getting a solicitor but I quite happy for her to involve a solicitor if she wants to and I'll abide with whatever the solicitor discovers if it comes to it.
